Description

Leionema oldfieldii is a small, compact shrub to 1 m (3 ft 3 in) high. The branchlets are more or less needle-shaped, with usually star to upright shaped soft hairs. The leaves are leathery, smooth, shiny, egg-shaped to oblong-elliptic, 7–15 mm (0.28–0.59 in) long, 2.5–6 mm (0.098–0.236 in) wide, flat with slightly rolled edges and finely scalloped toward the rounded apex. The inflorescence is a tight group of terminal, pale pink to white flowers on a fleshy, smooth pedicel about 2.5 mm (0.098 in) long with two small bracteoles near the base. The petals are elliptic, spreading, about 4 mm (0.16 in) long and smooth. The stamens are slightly longer than the petals. Flowering occurs from late spring to early summer.[2]

Taxonomy

This species was first formally described in 1858 by Ferdinand von Mueller and gave it the name Eriostemon oldfieldii and the description was published in Fragmenta Phytographiae Australiae.[3][4] In 1998 Paul G. Wilson changed the name to Leionema oldfieldii and the name change was published in the journal Nuytsia.[5][6]

Distribution and habitat

Leionema oldfieldii grows in mountainous areas of the south and west coasts of Tasmania.[2]

gollark: They say that no, you're measuring wrong, that hasn't been accurate since our deployment of GTech™ facilities into infinite binary trees.
gollark: (We moved beyond "divisions" long ago)
gollark: Really? I'll need to inform the GTech™ Meta-ontology Superlogarithm.
gollark: It contains two parts, and all the edges run between things in different parts.
gollark: Hmm, it is NOT that.
